UK CONTEMPORARY SILVER AND GOLD HALLMARKING:
HALLMARKS OF BRITISH SILVER AND GOLD

The British hallmarking system was widely modified in 1999 and some of the traditional marks became optional symbols applied only on request alongside the compulsory hallmarks.
Henceforth, future generation of collectors will fewer and fewer find the full set of hallmarks that for hundreds of years has characterized the British silver.

A Hallmark is now made up of three compulsory symbols with the addition of some voluntary marks.

COMPULSORY MARKS

The Sponsor's or Maker's Mark (Compulsory mark)

Indicates the maker or sponsor of the article. This mark consists of at least two letters within a shield (of various shape), and no two marks are the same.

Sponsor's or Maker's Mark RHF Sponsor's or Maker's Mark HBH

Metal and fineness (purity) mark (Compulsory marks)

Indicates the precious metal content of the object, and that it is not less than the fineness indicated. The fineness is indicated by a millesimal number (e.g. 925 is sterling). This number is contained in a shield of oval shape for silver and of octagonal shape for gold.

Date Mark (Voluntary mark)

After 1999 a date letter indicating the year of hallmarking can be applied voluntarily in addition to the compulsory marks. The date letters are the same on the four Assay Offices.

Commemorative marks (Voluntary marks)

Examples of commemorative marks applied to precious metals by the four UK Assay Offices are the "Millennium Mark" (used during 1999 and 2000), the "Golden Jubilee Hallmark", commemorating Queen Elizabeth II Golden Jubilee (applied during 2002) and the Diamond Jubilee Hallmarks commemorating Queen's Diamond Jubilee (applied from 1 July 2011 until 1 October 2012)

THE COMMON CONTROL MARK AND CONVENTION MARKS (Alternatively to previous marks)

After the sign of the International Convention on Hallmarks (1972) the UK Assay Offices can strike the Convention Hallmark which will then be recognised by all member countries in the International Convention. Conversely, Convention Hallmarks from other member countries are legally recognised in the UK and do not have to be re-hallmarked in the UK.
